Review on Effortless Air Line Set-Up: CEKER 1/4" NPT Push To Connect Fittings 6Mm Tube Od Air Line Fittings by Mark Tompkins

Don't waste your money on these junk fittings. No matter what I tried I couldn't get them to seal at all.UPDATE: The company that sells this product is now offering me money to remove this negative review. I value other peoples experiences and opinions on products. How else would we know if a product is any good? I would never let other people blindly buy this underperforming product without first being able to see my negative experience with it. I hope you consider this when looking at this product.
